- I gam a I. I I V z or;='B1;ackets;-- and I do. declare-the following toybe agfull, clear,f and exact description of the -,invention, ;such as will enable Others skilled'in thefart to whichlit appertains to make and use the'sameQ.

v5. i Thisginvention relates to an,-insulator I clamp .or bracket particularly intended for fuse'inclamping and maintaining glass or porcelain insulators-on cross/arms utilized yforjsupporting wires and jcables.

, ,The objectiof the-invention is to provide 7 a simple inexpensiveclain'p which is easily v and quickly applied to the cross arm without; necessitating a the "boring l of a hole throughfs id arm which-action naturally reolamp may be're'adilj loosened when desired and adjustedjfinfeitherdirection upon the 26 r Another object is toprovide a device of sults n weakening'of-the arm and which cross -arm.,

this character which does notrequire the use of athread or nut thereby providmg for-its quick application, and removal.

With. these and other objectsin view,the

. invention consists I of certain novel features of construction andthe comblnatlon and arrangement; of parts as will be hereinafter ,1. referred to'and claimed.

The'cro'ss bar 3 is hinged at onefend'to one end of the side bar 1 and on of Letters Iateht.

p r 1 at its other end is bent to form an inturned Y Be='it jknown-lthat l-{zlosnrn Zmcga citizen "ofatheig UnitedStates =residingat Lincoln, 3 's':; inf -the'g'county -of,Lancaster'rand State of Y f'Nebraska," have invented certain new and useful-.{Improvements in Insulator .Clamps into=parallel shank members 9 and 10 which are secured together and vcarry the insulator Arranged between these members 9 and 10 is a stiff piece of cloth or leather 11 through which the rivets which secure the members 9 and'lO together pass and which is designed to prevent sudden jars on the glass insulator carried by the shank. These shank members are concavo-convex in cross section with their rounded or convexed faces disposed adjacent to each other and the edges of said members are notched as shown at 12 to form a thread for engagement with the insulator I.

The side bars 1 and 2 are preferably provided with a plurality of longitudinally spaced apertures 13 punched inward to form roughened cross arm engaging spurs for holding the clamp in position when applied,

and the lower ends of these bars are bent. ,outwardly as shown at 13' to permit them to yieldably engage the cross bar 3 to provide for theapplication and removal of the bracket.

- When'a clamp constructed asabove de-,

scribed isto be applied to across arm the hookst and of the cross bar 3 and side member 2 are disengaged and the clamp is then 'seated on the cross armwith the bur like projections formedby the apertures 13 engaging said cross arm and the hooks 4 and 5 are then engaged by any suitable means and the clamp is securely held in positio'n onthe cross arm.

The insulator Imay be engaged with the shank formed by the members 9 and either before the clamp is applied to the cross arm or afterward asmaybe desired,

and when said clamp is engaged as above described, said insulator is held firmly and substantially vin position upon the cross arm.

Any suitable tool may be employed for connecting and disconnecting the hooked ends .of the clamp, the tool T being shown in Fig. l for this purpose. This tool T as shown comprises a rigid jaw 14 merging into a handle member 15 and having a pivoted outwardly bowed gripping jaw 16 Patented July 20,1915.
